New paper out (and to come) on cold water carbonate formation

Friend of the Ingalls lab, Eva Scheller, has a new paper out in Geology on early diagenetic textures within ikaite and monohydrocalcite (MHC) pseudomorphs that provide evidence for dehydration and, thus, primary cold water carbonate formation. A new geologically based proxy for freezing temperatures in ancient environments!  Link here: ​https://pubs.geoscienceworld.org/gsa/geology/article/doi/10.1130/G49312.1/607791/Guttulatic-calcite-A-carbonate-microtexture-that
